IMPROVEMENT IN NAIL-PLATE FEEDERS.

Specification forming part of Letters Patent No. 123390, dated JanuaryS0, 1872.

To all whom it may concern:

Be it known that we, H. B. PERKINS and E. C. PERKINS, of Oxford, in thecounty of Warren and State of New Jersey, have invented a certain newand useful Improvement in Nail- Plate Feeder; and we do hereby decla-rethe following to be a. full, clear, and exact description thereof',reference being' had to the accompanying drawing forming part of thesame, and in which- Figure l represents a side elevation of our improvednail-plate feeding machine. Fig.2 is a front view of the feeder proper.Fig. 3 is a transverse sectional view of the lower part of the feederpropem and Fig. 4 is a sectional view through the dotted line .r x ofFig. 2.

Similar letters of reference in the several figures have reference tocorresponding parts.

'I'his invention has reference to an improved nail-plate feedingmachine; and it consists of an automatic feeder susceptible of vibratorymotion, as well as being capable of clamping the nipper-rod for carryingit forward to permit of its plate having the nail cut from it,substantiallyY as hereinafter more fully set forth and claimed.

To enable. others to make and use our inven tion we will proceed todescribe it.

1n the annexed drawing, A refers to a frame, upon which one of' thecutters, a, with which the nail-plate is cut, is mounted or secured bymeans of an upright, al. B has reference to a conically-shapedreceptacle, which is made with a curvilinear support or bar, b, pivotedto a bar projecting from the frame A. This receptacle is to receive theplate from which the nail is to be cut, it being provided with sidegrooves b for that purpose. U C1 refers to the feeder properf which isconstituted of the uprights O O, connected together at the bottom, andof the cam-rod C1. The rod`C1 is pivoted to one of the uprights Obyforming its upper end with an axle or pivot, entering' an overhangingportion of said upright a-nd passing a screw'pivot, o, through the lowerhorizontal portion of' the said upright, and causing it to enter thesaid rod. The lower portion of the rod C1, is attached to a rod, D,which passes through the support b in such a nia-nner as to have lateralmovement, such being communicated thereto by being broughtin contactwith a beveled or inclined projection, c2, fastened to the upright al,when the receptacle B is operated or thrown back and forth. The upperpart of this rod C1 has a wedge-like shape, which acts as a cam, andgripes or clamps the nipper-rod E as the same is vib ated through thestriking of the rod D against itsproljection.

It will be seen as the rod Cl gripes or clamps the nipper-rod E thelatter will be carried forward so that its plate will be brought incoutact with the cutter of the nail-machine when the nail is to cut.

The movement of the rod D imparts a vibratory motion to the cam-rod C1,causing the latter, as hereinhefore stated, to gripe the nipper-rod. Thefeeder C O1 is hung upon centers c o within the frame O2, said framebeing ina-de up'on the outer end of abar, C, which isfirnilyboltedorotherwise secured to thesupport b. F is a bar or support,upon which the nipperrod E rests, and which is supplied with pins orprojl cctions e for guiding' it as it is lnoved f'orward. fis a metallicrod fastened tothe support F, and bent in such a manner as that it willmake a stop for and retain the feeder O C1 in its properposition orcounteract the action of the spring' j". f refers to a spring which isfastened at the upper end to the support F, and its lower end made topress or rest against the feeder C O1, and is for the purpose ofthrowing the latter back against the stop or rod fin the position itoccupied previous to its being thrown forward.

The power to operate the machine is applied at G, which communicatesmotion through the shaft having the eccentric q to the said eccentric,and the connecting-rod g', from which the said motion is conveyed to thereceptacle B.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

1. The combination with the reciprocating arm b, the rod 1), and thefeeding device O O1, said device being constructed and operating in themanner set forth.

2. The combination of the feeding device C C1, the support F, and thespring j", as and for the purpose set forth.

In testimony that we claim the foregoing as our invention, we hereuntosign our names in presence of two subscribing witnesses.
